Best praise vs top criticism for FiiO K7
Top Criticism
+2 pts“Well I have Organic and FiioK7 but because I use the iMac M4 with built in a powerful AMP then I am going to send the FiioK7 back to Amazon as I don't see much sound improvements over the internal iMac amp. I had tested the Arya Stealth before Organic and yeah the stealth are slightly more difficult to drive so the external amp was good to have. https://preview.redd.it/1pr33j3x8cye1.jpeg?width=4096&format=pjpg&auto=webp&s=8ab784a52a9bd64e41e09b5ebe48faac4333fde5”
